tBcmxSync or HAL process crash with Policy and DiffServ replacement enabled
tBcmxSync or HAL crashes during client authentication when Policy and diffserv configurations are pushed at least twice from Netsight Policy Manager or diffserv replacement configuration is manually modified on a switch
ACL hardware entries get corrupted when the diffserv replacement value is configured multiple times (either via Policy Manager or manually). This leads to a process crash and reboot when the corrupted entry is accessed while installing ACL rules for the a newly authenticated client.
Workaround: Disable diffserv replacement or do not modified the diffserv replacement configuration once it is configured.
A permanent fix for this is scoped for EXOS 22.3.1, via CR xos0067425.
Note that this can occur on backup and standby nodes in a stack as well as the master node.
